A qualitative study of positive psychological experiences and helpful coping behaviours among young people and older adults in the UK during the COVID-19 pandemic

While much research has focused on challenges that younger and older people have faced during the COVID-19 pandemic, little attention has been given to the capacity for resilience among these groups. We therefore explored positive psychological experiences and coping behaviours that protected mental health and well-being. Participants were 40 young people (aged 13–24) and 28 older adults (aged 70+) living in the UK during the COVID-19 pandemic. Interviews were held between May 2020 and January 2021. We generated six themes using qualitative thematic analysis, including: engagement in self-fulfilling activities, increased sense of social cohesion, personal growth, use of problem-focused strategies to manage pandemic-related stressors, giving and receiving social and community support, and utilising strategies to regulate thoughts and emotions. While all six themes were relevant both to younger and older adults, there were nuances in how each was experienced and enacted. For example, many older adults adjusted their routines given worries about virus vulnerability, while some young people experienced greater personal growth amidst increased awareness of mental health as they navigated the various lockdown restrictions.


Introduction
During the novel coronavirus (COVID-19) pandemic, the first UK lockdown was imposed in March 2020 [1], with people being ordered to stay at home unless for essential reasons such as grocery shopping or exercise. People aged over 70 were at first classified as especially vulnerable to the virus [2] and advised to stay at home earlier than other age groups at the start of the pandemic, while young people faced their own unique challenges owing to closures of schools, universities, and workplaces. Evidence suggests that many people in the UK experienced heightened levels of stress, anxiety and fear during the pandemic [3,4]. However, younger people on average scored highest on measures of loneliness, depression, anxiety, while older adults scored the lowest [5]. Nonetheless, many older adults still experienced complex and adverse psychological responses to events, including depression linked to loneliness [6] and fear arising consequences [25,26], and some have postulated that part of this is due to significant lifestyle changes owing to the pandemic [27], precarious employment [28] and education interuptions affecting long-term career planning [29]. Nonetheless, it has been observed that young people appeared to show quicker recovery from their symptoms compared to older adults during the initial stages of pandemic restrictions in the UK [30], thereby reflecting the potential for resilience of young people and the need to understand how older adults can be better supported over the longer term. Emerging qualitative findings have lent support to the premise of resilience of older adults and young people respectively as both groups drew on pre-existing and new coping strategies to protect their well-being during the pandemic [31]. Greater sense of coherence (SOC), which encapsulates an individual's ability to comprehend, manage and make sense of a new health threat, has been found to support well-being [32]. While it has been argued that SOC strengthens with age, adverse health impacts in old age may moderate SOC among older adults [33], hence age-related factors may influence capacity to cope with some of life's adversities.
Limited studies to date have explored in depth the experiences of young people and older adults during the COVID-19 pandemic through a positive psychology lens, to investigate the resources that people draw on to support themselves through pandemic-related distress. To address these gaps in the literature, we sought to answer the following question: "what were the positive psychological experiences or coping behaviours that protected mental health and well-being of young people and older adults living in the UK during the COVID-19 pandemic?"

Design
This study forms part of the University College London (UCL) COVID-19 Social Study (CSS), which was the largest panel survey and qualitative interview study of the psychological and social experiences of people in the UK during the COVID-19 pandemic [34]. For the current study, we performed secondary qualitative analysis of 68 interview transcripts reporting the perspectives and experiences of young people (aged [13][14][15][16][17][18][19][20][21][22][23][24] and older adults (aged 70+). This paper follows the Standards for Reporting Qualitative Research (SRQR) reporting guidelines [35].

Procedure
Participants were recruited through the CSS e-newsletter, social media, personal contacts, and partner organisations (i.e., third sector services) working with older adults or young people. Eligibility criteria included: aged 70+ or 13-24, living in the UK, and fluent in English. Given the link between certain demographic factors and mental health during the pandemic [30], convenience and purposive sampling strategies were employed to include individuals of diverse age, ethnicity, sex, marital status, living situation and employment status. All participants completed a self-report demographics questionnaire on age, ethnicity, sex, marital status, living situation, employment status, physical and mental health conditions. Semi-structured, one-to-one interviews, lasting between 14 to 85 minutes (M = 45 minutes) were conducted between May 2020 and January 2021, which included the first and second national lockdown in the UK where people experienced cycles of tightened and eased pandemic-related measures (see S1 Table). Interviews were conducted by postgraduate-level, male and female, qualitative health researchers via telephone or video call.
Interviews followed a Topic Guide (see S1 Fig) designed to encompass a range of topics which have been covered in other papers with young people and older adults [7,29,36]. The Topic Guide was developed from supporting theory regarding social networks and SOC [23,32]. Specific questions were asked to elicit responses on positive experiences during the pandemic and behaviours that helped people cope (see S2 Fig), which formed the focus of this study-although participants also spoke of factors negatively impacting well-being which are reported elsewhere [7,29]. Participants were offered a £10 shopping voucher as a token of gratitude.

Research ethics
Ethical approval for the study and research procedure was obtained from the UCL High Risk Ethics Committee (ProjectID:14895/005). We followed best practice guidelines outlined by the Health Research Authority for research involving children and young people when developing our research protocol for obtaining participant consent [37]. We sought written informed consent from participants aged 16 and over. In cases where participants were aged 13-15, they were asked to provide their verbal and written assent and have a parent provide their verbal and written informed consent. All data were held securely and confidentially. Our research protocols were aligned with the principles of the Declaration of Helsinki [38].

Data analysis
Interviews were audio-recorded, then transcribed verbatim. Transcripts were checked before importing into NVivo 12 [39]. We carried out qualitative thematic analysis with a predominantly deductive and theory-driven orientation during theme and code development [40]. In contrast to "Big Q" qualitative research, which tends to be more exploratory and inductive in nature [41], our analysis practices aligned more closely with structured, postpositivist-leaning "small q" qualitative research as distinguished by Braun and Clarke (2021) [42]. The lead author (LO) read through all transcripts to ensure completeness of data analysis. While LO coded all transcripts, a second researcher (AM) double-coded three transcripts at the beginning of data analysis and both authors reviewed these identified codes to ensure consistency before completing the remainder of the coding. A deductive coding approach was initially used, whereby a coding framework was first established based on supporting theory on positive psychology and coping [18,21], and this framework was applied to each transcript through line-by-line coding. The coding framework was then refined iteratively as new concepts were identified by LO. Contradictory remarks and context surrounding codes were noted to draw out subtle nuances. Codes that share a common meaning or concept relevant to the research question were clustered to create themes. Themes and subthemes were developed and regularly discussed between three researchers (LO, EP and AM) throughout the analysis stage to ensure appropriate categorisation of codes. NVivo Crosstab query was used to facilitate analysis of themes across the two age groups.
Themes and corresponding sub-themes on positive psychological experiences and helpful coping behaviours are illustrated in Tables 2 and 3 respectively and described below. Many participants described several positive psychological experiences including engagement in selffulfilling activities, increased sense of social cohesion and greater personal growth. In addition, many spoke of engaging in various helpful coping behaviours including use of problemfocused strategies to manage pandemic-related stressors, strategies to regulate thoughts and emotions, as well as giving and receiving social and community support. Both groups said they enjoyed more free time for leisure and to develop new skills.
Young people found renewed sense of competence being able to sharpen their skills.
Older adults found opportunity to rekindle old hobbies and immerse themselves in leisure activities.

Opportunity to organise affairs
Both groups said they found opportunities to incorporate time for more wellness activities in their lives.
Some young people expressed feelings of satisfaction having the opportunity to spend more time on wellness activities. E.g., "I suppose kind of a sense of satisfaction that it's giving me the space to finally get around to fixing certain aspects of my life.
Sorting out routines and getting finally around to doing the exercise. . . meditating, the sort of general wellness personal admin stuff. I'm glad that's happened. . ." (P56, aged [18][19][20][21][22][23][24] Some older adults found opportunity to catch up on overdue tasks in their personal life e.g., sorting out finances and medical care concerning their end of life. E.g., "I've been thinking a lot more about the fact that I'm not going to live that much longer, which I hadn't thought of before, that much. . . .It's something I've done work on before, getting papers in order and writing explanations and things like that, but now that I've got the time to do it, and I'm thinking about it." (P14, aged 75-79)

Theme 2: Increased sense of social cohesion
Description: With the shared experience of going through a pandemic, many participants described a greater sense of togetherness with their community, and more than half of participants reported feeling closer to family and friends as a result of more frequent or consistent contact given a 'greater spirit of loneliness'.

Heightened compassion and connectedness
Both groups discussed the desire to be more intentional about strengthening or rekindling relationships into the future.
Some young people described increased closeness through consolidated friendship networks. E.g., "it (the pandemic) was like a friends filter" (P27, aged 18-24); "There are some people I haven't necessarily missed not seeing them.. . . I've connected with the people I've needed to. So, in a way my network it's become clearer and seems closer." (P37, aged [18][19][20][21][22][23][24] Some older adults discussed reconnecting with friends or family whom they have grown apart from. E,g., "Yes, those old friends that you'd taken for granted, or didn't seem particularly relevant any more, to realise that if that connection can be rekindled after such a long time, meaningfully, it was worthwhile. So, it's going to be worth making more of in the future, making more effort about in the future. Family, it makes me realise that I do really love them and miss them" (P07, aged 70-74)

Greater sense of community
Both groups discussed a greater sense of belonging through the "Clap for Carers" (a social movement in appreciation of people working for the UK's National Health Service) and increased interaction with neighbours.
Some young people reported being "more aware of what's going on in my community" (P40, aged 18-24) amidst a greater sense of community. E.g., "I think another positive of the pandemic is that it's brought more people together which sounds cringey but what I mean by that is definitely with our neighbours we've become more close because we're at home all the time. So, a lot of the time if we bake something, like a cake or something, we would give some to our neighbours and then they would do the same for us." (P50, aged 13-17) Some older adults described how the "Clap for Carers" facilitated increased interaction with neighbours. E.g., "We relate a bit more to the local neighbours. . . . They all come out and clap every Thursday night at 8 o'clock. . . So, chatting more to the neighbours is probably the main positive." (P13, aged 80-84) Theme 3: Greater personal growth Description: Some participants recognized self-improvement to their own skills, knowledge, personal qualities and outlook.

New outlook on gratitude
Both groups described greater appreciation for outdoor activities, use of digital tools to keep in touch with friends and family, and favourable living conditions.
Young people discussed a greater sense of gratitude towards their existing friendships or romantic relationships.
Older adults described feeling fortunate to be retired and financially secure.

(Continued )
Positive psychological experiences 1 Engagement in self-fulfilling activities. 1.1 Opportunity for leisure and exploration of new skills. Many participants described enjoying more free time for leisure and to develop new skills, leading to feelings of improved well-being and satisfaction levels. Among older participants, some found that a slower pace of life during the pandemic allowed them to rekindle old hobbies and immerse themselves in leisure activities: 'I've always loved reading so I've been able to get on with as much reading as I want. . . .to actually just sit for a couple of hours reading and not feel guilty.' (P06, aged 70-74) Among younger participants, some expressed a renewed sense of competence being able to sharpen their skills, 'I think I've improved on my music a lot more because I had more time to practice' (P50, aged [13][14][15][16][17]. Some quoted reduced academic pressure or being financially secure as facilitators for being able to learn new skills. I haven't needed to worry about doing a job so I have money next month. So in a way, I've been able to relax a bit which has been really nice and not focused everything on my work. So that is where I've been able to dedicate time to help with anything outside and I actually produce video content for those and learn new skills when it comes to software. . . (P26, aged [18][19][20][21][22][23][24] 1.2 Opportunity to organise affairs. Some older adult participants described having the opportunity to catch up on overdue tasks in their personal life including home fixes and 'sort (ing) out paperwork' for their finances and medical care concerning their end of life.
It (the pandemic)'s given me the focus to get into the garden and get on with that because for seven years I was at best maintaining it. Last year I made a big effort to get on top of it. . . .and the lockdown has enabled me to get on with that. (P06, aged 70-74) Both young and older people found opportunities to incorporate time for more wellness activities in their life as they began to value their health and well-being more.   Table 3. Themes and subthemes on helpful coping behaviours, with summary of similarities and differences between young and older participants.

Theme/ Subthemes Overall Young People Older Adults
Theme 4: Use of problem-focused strategies to manage pandemic-related stressors Description: Many participants discussed how the pandemic has brought about new stressors in their daily lives and highlighted how coping behaviours targeted at such stressors have been helpful.

Managing intake of pandemic-related news
Both groups found it helpful to intentionally minimise consumption of news.
Some young people discussed minimising consumption of news in the context of lack of information and certainty about schooling and exams. E.g., "Like with exams and everything, we didn't know anything that was going on and we didn't know when things would be back to normal.

Adopting a new routine
Both groups discussed having to adapt their lifestyle to 'a socially distant world' and the benefits of a routine.
Young people described how adopting a new routine during the pandemic afforded a sense of structure and helped them feel 'more under control', mitigating the potentially negative impact of remote studying/working from home which blurred study/work-life boundaries.
Older adults described a new sense of purpose and achievement in keeping up a routine as similar as possible to that of prepandemic times while allowing themselves the flexibility to 'swap things around'

Theme 5: Use of strategies to regulate thoughts and emotions
Description: Nearly all participants discussed a range of coping strategies to regulate unpleasant thoughts and emotions triggered by circumstances of the pandemic.

Engaging with arts and digital mental health apps
Both groups discussed how engaging in arts activities (e.g., participating in a "Zoom choir" and listening to music) helped soothe feelings of anxiety or worry and elicited positive emotions.
Young people discussed how digital mental health apps assuaged feelings of worry about uncertainty of their studies and future career.
Older adults missed engaging with arts and cultural activities in-person but most found it helpful being able to continually engage in such activities from home through virtual means during the pandemic.

Being outdoors and connecting with nature
Both groups reported heeding government guidance that allowed outdoor exercise during lockdown and found it helpful to get 'fresh air' outdoors and connect with nature.
Some young people spoke about how getting out helped them unwind after a long day of working or studying from home. E.g. "I think generally the way that I cope with my stress is going out for walks. . . .I spend most of my time indoors, but I think sometimes when you spend too much time inside you just need to go out and breathe fresh air and get a completely different perspective. . . .there's just something about staying inside and breathing the same air, I know that you get stuck in your head and you get stuck in your problems. And I feel like when you go outside and you see the outside world, you see that the world is bigger than your problems." (P64, aged [18][19][20][21][22][23][24] Some older adults spoke about how caring for their garden was beneficial to their physical and mental wellbeing. E.g., "And because of Covid I've had to spend more time in the garden and I've certainly found it therapeutic, learning a little bit more about how you get things to grow. . . .And though I'm not becoming a good gardener, because I haven't got fast enough learning skill, I have found being in the open air in the garden very helpful and I think Covid's arrival when it happened, was a huge advantage." (P25, aged 75-79)

Theme 6: Giving and receiving social and community support
Description: Many participants discussed how engaging with social support structures, within their social circles and the wider community, was valuable to good mental health and well-being.

Engaging with interest-based social groups
Both groups found it rewarding to engage in interest-based social activities.
Young people described how engaging in online multiplayer games strengthened their relationships with friends or expanded their social circle as such games facilitated 'friendly competition' and allowed them to enter into a lot of discussions.
Older adults reported engaging in groups such as walking groups, online writing groups or photography groups to keep their mind and/or body active while maintaining social connections.
(Continued ) 2 Increased sense of social cohesion. 2.1 Heightened compassion and connectedness. More than half of participants reported feeling closer to family and friends as a result of more frequent or consistent contact, given a 'greater spirit of loneliness' and heightened sense of compassion for others. Many young and older participants discussed the desire to be more intentional about strengthening or rekindling relationships into the future; 'So, it's going to be worth making more of in the future, making more effort about in the future. Family, it makes me realise that I do really love them and miss them.' (P07, aged 70-74) Among young participants, some described increased closeness through consolidated friendship networks as 'it (the pandemic) was like a friends filter' (P27, aged [18][19][20][21][22][23][24]; 'There are some people I haven't necessarily missed not seeing them.. . . I've connected with the people I've needed to. So, in a way my network it's become clearer and seems closer.' (P37, aged [18][19][20][21][22][23][24] 2.2 Greater sense of community. With the shared experience of going through a pandemic, many participants described a greater sense of community, especially during the first national lockdown; 'During the initial bits of lockdown, there was quite this sense of solidarity, wasn't it? This general feeling of. . . this sucks, but we're all in this together. . . .That was really nice.' (P39, aged [18][19][20][21][22][23][24] Several young and older participants discussed a greater sense of belonging through the "Clap for Carers" (a social movement in appreciation of people working for the UK's National Health Service) and increased interactions with neighbours; 'We relate a bit more to the local neighbours. . . . They all come out and clap every Thursday night at 8 o'clock. . . So, chatting more to the neighbours is probably the main positive.' (P13, aged 80-84) 3 Greater personal growth. 3.1 New outlook on gratitude. Several young and older participants described a new outlook on gratitude, as they had come to 'appreciate all the smaller things' in view of restrictions that were imposed during the pandemic, including greater appreciation for outdoor activities, use of digital tools to keep in touch with friends and family, and favourable living conditions (i.e., having a garden). Several older participants described feeling fortunate to be retired and financially secure in comparison to many younger, working adults who may be struggling with job security during the pandemic.
We're retired so we have our pensions, so we're not having to worry about losing our jobs, losing our income or finding a way in which to work in order to be able to earn some money when there can't be any contact between people. So I feel very fortunate that we're not faced with that problem. (P03, aged 70-74) Among young participants, many discussed a greater sense of gratitude towards their existing friendships or romantic relationships, given the challenges faced with meeting new people during the pandemic.

Increased feelings of resilience.
Having navigated the unexpected challenges of the pandemic, some young and old participants found that they felt more resilient; 'I think I'm stronger than I thought I was, and that I can do things, possibly, I didn't think I would be able to do, and I've coped better than I thought I'd be able to cope.' (P08, aged 70-74). Some young participants reported having gained the ability to take better care of themselves, thereby feeling more prepared to face future hardships; 'I now know how important it is to have good mental health, constantly. So, that if anything like this were to happen again, I would be prepared.' (P51, aged 13-17) Some participants with physical or mental health conditions discussed feeling proud of their capacity to manage their condition amidst the challenges of the pandemic.

Helpful coping behaviours 4 Use of problem-focused strategies to manage pandemic-related pressures. 4.1 Managing intake of pandemic-related news.
Given the changing circumstances during the pandemic, some participants (both younger and older) acknowledged that 'cutting down on news bulletins but nevertheless, making sure that one is in touch with what is happening, is probably advantageous' (P04, aged 85-90). Some found it helpful to intentionally minimise consumption of news in view of adverse impacts on their mental health; 'whenever I read the news it's always just bad things. It always makes me worry, so just staying away from that helped as well.' (P50, aged [13][14][15][16][17] 4.2 Adopting a new routine. As the pandemic resulted in restrictions to usual activities, participants reported having to adapt their lifestyle to 'a socially distant world'. Around one-third of young participants described how adopting a new routine during the pandemic afforded a sense of structure and helped them feel 'more under control', mitigating the potentially negative impact of remote studying/working from home which blurred study/work-life boundaries; 'I think the important things to me over lockdown have been actually to give myself a bit of a schedule and wake up by around 7:00, 7:30 in the weekdays than actually have a lie-in.' (P26, aged [18][19][20][21][22][23][24]. Furthermore, some discussed how online platforms facilitated self-paced learning which afforded better flexibility and ability to sustain a routine. Some older adult participants described a new sense of purpose and achievement in keeping up a routine as similar as possible to that of pre-pandemic times while allowing themselves the flexibility to 'swap things around'. I do make myself behave as if, yes, I'm going out to do something. Even if it's only to go for a walk, or do the garden, that is my thing and I'm going to do it properly. . . . and I feel, therefore, positive that I have done things, and achieved things. (P08, aged 70-74) arts and cultural activities in-person but most found it helpful being able to continually engage in such activities from home through virtual means during the pandemic. Participants reported that engaging in arts activities such as watching performances online or via television, participating in a "Zoom choir" and listening to music helped soothe feelings of anxiety or worry and elicited positive emotions.
And from Sky Arts on my big TV that has a few programmes a week. . . .compared with how often I might have been going to the theatre or cinema. I've been able to get performances there. It's kept me happy. (P11, aged 70-74) Several young people reported worries about uncertainty of their studies and future career; however, digital mental health apps assuaged some of these feelings by helping them to become more aware of strategies to improve their mental health.

Being outdoors and connecting with nature.
The majority of participants reported heeding government guidance that allowed outdoor exercise during lockdown and found it helpful to get 'fresh air' outdoors, with several describing easy access to green spaces as a facilitator for these coping behaviours. Some young participants spoke about how getting out helped them unwind after a long day of working or studying from home; 'I did go out for the once-a-day exercise. I usually tried to do it after work just to give me that break to change my mindset from work mode to coming back to relaxing.' (P36, aged [18][19][20][21][22][23][24] While the pandemic seemingly brought everyday life to a standstill, several participants, young and old, found it 'therapeutic' connecting with nature, where some participants described that seeing plants grow symbolised a sense of time passing. Having plants grow within the house is an amazing way to keep track of time when it all seems so monotonous because it changes, it grows, and you are there. It's a little project and I found that it's so fantastic for me. I've really loved having my plants. (P26, aged 18-24) 6 Giving and receiving social and community support. 6.1 Engaging with interest-based social groups. Many participants found it rewarding to engage in interest-based social activities. Among these participants, several older adults reported engaging in groups such as walking groups, online writing groups or photography groups to keep their mind and/or body active while maintaining social connections.
Oh, and the other one I'm sort of involved, I was before lockdown, in a creative writing group. . . we've been doing that on Zoom.. . . . So that's as a little social thing and keeping the mind active as well. Keep that going, yes. (P22, aged 75-79) Amongst young participants, many described how engaging in online multiplayer games strengthened their relationships with friends or expanded their social circle as such games facilitated 'friendly competition' and allowed them to enter into a lot of discussions; 'Since lockdown started, I've been involved in playing a lot more social board games online. . .and really built a wonderful community of people from all around the world who are really interesting people. . . .It's a nice, different tangent.' (P26, aged [18][19][20][21][22][23][24] 6.2 Volunteering and community participation. Several young participants sought out inperson volunteering, such as with foodbanks and delivering essentials to people who are shielding, as 'another excuse to get out of the house' (P57, [18][19][20][21][22][23][24] while also feeling helpful and needed.
The only thing that I wasn't doing that was fully rigid with the routine of lockdown was volunteering at the foodbank. And that was because I thought I would just absolutely go crazy if I had to stay in the house the whole time. . . I just genuinely feel like everything that I do at the moment is really worthwhile to someone, it's always helping someone else in some way. . . (P40, aged [18][19][20][21][22][23][24] Among older adult participants, some discussed finding a sense of usefulness while keeping their mind busy by participating in surveys/studies.

Discussion
In this qualitative study, we investigated positive psychological experiences and helpful coping behaviours perceived by young people and older adults in the UK in the first year of the COVID-19 pandemic. There were many similarities in the broad types of psychological experiences that younger and older adults had, as well as similarities in the broad coping behaviours employed, although the details of how these experiences and behaviours were perceived and enacted varied by age. Nonetheless, we identified several common potential components of future interventions to support both young people and older adults in times of pandemics, including activities that foster a sense of community and connectedness (such as "Clap for Carers"), resources that support a stable routine (such as self-paced online learning) and platforms that offer digital means of engaging with hobbies (either on the internet or via mobile phone apps).
One of our salient findings was an increased sense of social cohesion across age groups, congruent with evidence indicating greater gestures of solidarity [16] and the heightened value of personal relationships during the COVID-19 pandemic [14], which reinforce the value of platforms that foster these activities to take place. Our results build on previous research by suggesting how a heightened sense of loneliness and engaging in collective action may encourage a greater community spirit across the age groups amidst social distancing restrictions. While it has been suggested that many young people suffered from loss of social connections during the pandemic [29], a novel finding from our study is that some young participants acknowledged how social restrictions have inadvertently weakened some social ties yet strengthened other key friendships, which facilitated a sense of increased relational closeness. Results suggest that many participants felt that their social networks evolved towards strengthened relationships and stronger community ties, which in turn, improved perceptions of overall well-being.
Several pandemic-related experiences reported by participants appeared to be shaped by their different life stages (i.e., young versus older adulthood) and these factors further shaped subsequent coping behaviours. For instance, younger participants highlighted reduced academic pressure or being financially secure as enablers to exploring new skills. Emerging evidence suggests that younger people, as compared to older adults, had more financial worries during the pandemic [43] and having financial support has been shown to be a protective factor for coping among young people [44] -hence there is additional need for financial and occupational support toward young people in the future, coming out of the pandemic. The protective role of financial security also resonated with some older participants who described feeling grateful to be retired and financially secure compared with other groups. Moreover, many participants across both age groups discussed a greater sense of appreciation for smaller things in life during the pandemic, reflecting a sense of gratitude which can encourage psychological resilience [45]. Furthermore, our finding that some participants felt a greater sense of resilience within themselves supports the argument that adverse circumstances of living (such as those present during the COVID-19 pandemic) may encourage personal growth and resilience [46]. Our results expand previous findings of personal growth among young people during the pandemic [47] by suggesting that young participants experienced personal growth from having recognised and developed their ability to protect their own mental health in the future.
With regards to helpful coping behaviours, we noted some similarities and differences across age groups. Several young and older participants expressed mental health benefits of engaging in arts and cultural activities remotely, consistent with existing evidence for the use of arts to help cope with emotional experiences during the pandemic [48]. Our results further suggest how increasing digital access to arts during the pandemic is especially valuable to older adults who may otherwise be less likely to engage in arts through digital means as compared to young people. Among young people, our results on the use of digital mental health apps in supporting mental health highlights the promise of such tools in equipping individuals with self-care skills in the future [49]. Evidence suggests that engaging with nature is linked with more positive emotions and fewer symptoms of anxiety, particularly amid stringent lockdown measures during the pandemic [50]. We found that the main differences in this and with several other coping behaviours between young and older age groups were attributed to workrelated stress. For instance, some young participants specifically highlighted how spending time outdoors helped them de-stress while adapting to remote working and learning during the pandemic. This could be taken into account by employers and education providers in the event of future social distancing restrictions.
In view of evidence which suggests increased volunteering behaviours in the UK during the COVID-19 pandemic [51], our findings highlight potential age differences in one aspect of volunteering whereby in-person volunteering was especially prominent among young participants. Erikson's stage theory of psychosocial development [52] posits that adolescent years present a conflict of identity versus role confusion whereby adolescents navigate their independence and develop a sense of self. In-person volunteering may have facilitated such aspects of growth as young participants described gaining a sense of being useful while escaping the confines of home during the pandemic. Additionally, young people may have been less worried about their risks from COVID-19 when compared with older adults [53], hence readily sought out in-person volunteering opportunities. Furthermore, a novel finding of our study is that some older adult participants found it beneficial for their wellbeing to volunteer for research surveys during the pandemic, highlighting how volunteering opportunities must be accessible to all age groups. This extends existing literature that being useful in this manner could add meaning to individuals' lives [54], by potentially helping people to make sense of life during the pandemic.

Strengths and limitations
This is the first known study that qualitatively explored positive psychological experiences and helpful coping behaviours perceived by young people and older adults in the UK during the COVID-19 pandemic. Purposive sampling enabled greater demographic diversity among participants, which facilitated rich nuances about the experiences of participants that could be targeted in future public health interventions. However, the socioeconomic background of participants was not known, and this may have biased certain findings. While in the present study (where participants were predominantly White British) we found a greater sense of community, some studies indicated reduced sense of social cohesion among some ethnic minority groups in the UK, as the pandemic had more adverse impacts in these communities [55]. Our data collection period may also have influenced the results of our study, given that interviews concluded in January 2021, less than one year since the start of the pandemic as declared by the WHO [56] -hence young and older adults' experiences may be different at later stages of the pandemic. Moreover, the sample may be biased towards people who were less severely impacted by adversities during the pandemic or coping better than others who were unable to participate. Therefore, we cannot assume the transferability of our results to all other contexts and the coping behaviours may not reflect that of the broader population of older or young people.

Implications
This study highlights some key implications for coping during a pandemic and beyond. First, digital mental health apps may be a valuable tool to support mental health during crisis situations where access to formal mental health support is limited, therefore, further research on their potential is warranted. Second, the benefits of spending time outdoors and connecting with nature may have policy implications for access to green spaces during the pandemic as well as implications for green social prescribing to support well-being [57]. Third, present findings on positive psychological experiences and coping behaviours that protect well-being suggest scope for an extended version of the PERMA model of positive psychology: PERMA-H model [58], which incorporates the facet of positive health. Our findings support the idea that a positive psychology model that includes physical and psychological health may be especially relevant in the context of an infectious disease pandemic to understand well-being more holistically. Moreover, further research is warranted to understand the experience of various socioeconomic groups and ethnic backgrounds and capture experiences over time given the fluctuating nature of the pandemic.

Conclusions
While the COVID-19 pandemic has presented many challenges in various aspects of life of young people and older adults, participants' use of various coping strategies reflect their resilience. In brief, participants described coping behaviours that protect their well-being, with older participants adapting lifestyles in the context of worries about their vulnerability to COVID-19. Moreover, this study highlights positive psychological experiences during the pandemic such as heightened connectedness and increased feelings of resilience. While all six themes were relevant both to younger and older adults, there were nuances in the experience and enactment of behaviours between each age group. These findings may be useful to guide tailored support for well-being among young and older age groups during a pandemic and post-pandemic recovery.
